To all whom it may concern:

Be it known that I, BROR J. LINDGREN, a citizen of the United States of America, and a resident of New York, borough of Brooklyn, county of Kings, and State ofNew' York, haveinvented certain new and useful Improvements in PerforatingVIachines, of which the following is a s ecification.

My invention re ates generally to perforating-machines used to perforate a sheet of m aterial so as to convert it into a screen or the like, and has moreparticularreference to an showing the ef improved mechanism for feeding the sheet both in a forward and a transverse direction. To this end the invention comprises the features of construction and combination of parts, as will more fully hereinafter appear.

In the accompanying drawings I have embodied my invention in a suitable form, but changes of construction and omission of parts may of course be made without departing from the spirit of the invention.

In the said drawings, Figure 1 is a front elevation of a machine embodying my inven tion. Fig. 2 is a side view of the machine looking in the direction of the arrow 2 in Fig. 1. Fig. 3 is a detail view of the mechanism for operating .the advance feed independently of the punch and transverse-feed mechanism looking in the direction of the arrow 3 in Fig. 2. Fig. 4 is a side view of the machine looking in the direction of the arrow 4 in Fig. 1.

transversefeed acts every time or periodically and the advance feed acts every other time or semiperiodically. Fig. 18 shows the j Fig. '17 shows. the effect produced when the eflect produced when the advance feed acts periodically and the transverse feed acts semiperiodically.

Similar characters or reference indicate corresponding parts in the different views.

In perforating a sheet of this kind the perforations are very close together, as best seen in Fig. 16. The result is that where a number of punches act together the dies will be too weak to stand the strain and will break between adjacent holes if one complete row of closely-adjacent perforations is punched out at one time. Q

The chief object of my invention is to pro duce a structure adapted to punch alternate perforations in one row, leaving-a wide space between adjacent perforations, and then to perforate the intervening space in the same row on the next stroke of the machine. By this means the perforations are punched as closely adjacent as in the old style iw'ithout subjecting the dies to an undue shock causing the same to break.

The present machine contemplates mechanism whereby the advance and transverse 'feeds are adjustable independently of each other, so that the sheet can be fed forward every time or every other time and fed transversely every time or every other time, or both the forward and transverse feed can take place with every stroke of the machine simultaneously at will the same machine The nature and scope of the invention will best be understood by inspecting Figs. 15, 16,

In Fig. 16, for instance, the pertervening space. Then the sheet wil be fed transversely on the next stroke ofthe-machine and the perforations 2 will be punched out, thus completing the first transverse row. On the next stroke of the machine the perforations 3 will. be punched out by the sheet being fed in a forward direction. The sheet is then fed transversely and the perforations 4 are punched out. In this case,.therefore, the advance and transverse feeds are operated .semiperiodically and alternately of' each 2 other. In Fig. 17 the perforations 5 are first punched out. Then the sheet feeds transversely and the perforations 6 are produced. The sheet is then fed both forward and trans versely and the erforations 7 are punched out, after which t 1e sheet moves transversely again and is erforated at 8. Here the sheet therefore is ed transversely every time, but forward every other time only, or transversely periodically and forward semiperiodicaily. In Fig. 18 the reverse takes place and the sheet is "fed forward periodically, but transversely semiperiodically. In Fi 15 I have shown the old style, where the s eet' is fed both forward and transversely periodically. .The-dotted line indicates the path of travel in these several figures.

The general nature, object, and desired result of my invention being now understood, I shall proceed to describe the structure for producing these results.

1 indicates a framework for properly supporting the several parts comprising the machine. In this framework there are a plurality of dies, preferably arranged in one line only. and a corresponding number of punches mounted in' the slider 2 and operated by means of the main shaft 3. The dies and punches are s aced .a distance apart somewhat greater t an the size of the perforations.

The advance-feed mechanism comprises in part a plurality of opposed sets of sheet-gripping rollers 4. In this instance there are four sets, only two of which can be seen. These rollers are knurled, as shown, and are adapted to seize the edge of the sheet to feed the same forward. Suitable means are provided for operating these advance-feeding rollers intermittently in one direction only. In the present instance these means take the follow ing form: Extending transversely of the machine are two advance-feed shafts 5 and 6 for each two sets of rollers. The shaft 5 is operated periodically or semiperiodically at will by suitable-driving means and proper connections. In this case there is mounted fast on the counter-shaft 7 a crank .8 and also a collar 9. Mounted loosely on the hub 10 of the crank 8 is a pinion 11, meshing with the gear 12 on the shaft 66. The proportion between the gear 12 and pinion 11 is such that the former makes one revolution to every two revolutions of the latter. In the collar 9 there 'is a spring-seated pin 13, normally adapted to engage in the aperture 14 of the pinion 1 1, so as tocause the crank 8 to move with the pinion. Pivotcd adjacent to the collar 5) is a latch 15 in the form of a bellerank', J'iaving one arm 16 adapted to engage in the aperture 17 of the pin 13 to move the latter out of engagement with the pinion, thereby disconnecting the crank 8 and pinion 1 1. The 01 her arm 13 of the latch 15 is pro vided with a friction-roller 1. 9, engaging with the cam 20 on the shaft 66'. This cam is so constructed that it will move the latch out of ermost lposition.

pin 13 on every other revolution of the pinion 11, thereby operating the crank 8 semiperiodically. The arm 16 is normally held in engagement with the pin 13 by means of the spring 21 on the rod 22. This rod 22 is connected to the eccentric 23 by means of the rod 24. When the handle 25 of the co centric is operated in one direction, the arm 16 is moved out of the pin 13 and the crank 8 is operated periodically, owing to the fact that thepin 13 will be in constant'engage ment with the pinion 11.

The crank 8 is provided with'connectingrod 26.for operating the pawl 27, engaging with the ratchet 28 on the shaft 5, thus driving the latter intermittently in one direction periodically or semiperiodically at will. The

. shaft 5 carries a gear 29, meshing with the intermediate 3(), which in turn imparts its motion to the gear 31 on the shaft 6.

Mounted on the guides 32 of the framework and embracing the shafts 5 and 6 are four feed-roller frames 33, two on each shaft and one for each set of rollers. As these feed-roller frames are alike in their construc tion, only one will be described. The feedroller frames 33 are provided with the housings 34, carrying the movable boxes 35, supporting the feed-rollers 4. Mounted on theshaft 5 (or 6, as the case may be) is a gear 36, capable of a lengthwise movement on the said shaft 5 by reason of the spline 37. Mounted on the studs 38 of the rollers 4 are the pinions 39 and 40, the pinion 39 receiving 'pinion 42, which in turn meshes with the gear 36. By the foregoing means the feedrollers are operated from the crank 8 to feed the sheet in a forward direction.

Above the feed-roller frame is pivoted the arm 43, connected with the boxes of the u er rollers. The said boxes are normally held in their lowermost position by reason of the spring 44 connected to the arm 43. Means are provided, however, for lifting the 11 per feed-rollers up and out of contact with t 1e lower feed-rollers, taking the form of a transversely-extending spindle 45, passing through the ears 46 and provided with a flat surface 47 and a round surface 48, against which the arm 43 is pressed by the spring 44. At one end of the spindle there is a handle 49 for turning the said spindle. When this spindle has its flat surface 47 against the arm 43,- the upper feed-rollers will he in their low- When it is desired to raise the sai rollers out of contact with the lower rollers, the handle 49 is manipulated, thereby turning the round surface 48 of the said spindle adjacent to the arm 43, thereby depressing one end of the latter and raising the rollers. A cam or any other means could of course be used for the same purpose. There are two of these spindles 45, one for each two I just thefeed-roller-frame, the bolt 51 is loos- Fig. 10.

sets of rollers in transverse alinement with each other.

Formerly it has been customary in the art to have bars extending the full length ofthe machine transversely for feeding the sheet:

By the employment of side feed-rollers for gripping the side edges of the sheet only I am enabled to adjust the machine to different widths of sheets in the following manner: Extending transversely of the machine are two transverse-feed shafts 50, to which are attached the feed-roller frames by means of the bolts 51 and sleeves 52, as shown best in Mounted on the framework is a transverse rack' 53, and carried by each feedroller frame is a pinion 54, mounted in the eccentric bushing 55. This eccentrie'bushing 55 carries a handle 56 for turning the same so as to.bring the pinion54 in and out of mesh with the rack 53. When it is desired to adened and the pinion is brou ht into mesh with the rack. A wrench is t en applied to i 1 means of the cross-head 58.

the square 57, thereby turning the pinion and causing the feed-roller frame to slide on the guide on theframe and over the advancefeed shaft and transverse-feed shaft. Each feed-roller frame is adjustable independently of the other. In traveling the feed roller frame carries the o eratin -pinions and gear 36 along with it. BVhen the desired adjustment has been obtained, the pinion 54 is lowered out of mesh with the rack 53 and the bolt 51 is tightened.

The sheet is moved transversely periodici ally or semiperiodically by imparting a reciprocating motion to the transverse-feed shafts 50, to which shafts the feed-roller frames are attached. This motion is imparted to the transverse-feed shafts in this instance in the following manner: The two shafts are connected together on one side of the machine by This cross head is provided with a pin 59; embraced by the bifurcated arm 60, attached to the rock-shaft 61, disposed at right angles to the shafts 50.

i Located above the shaft 61 is a shaft 62, connected to the said rock-shaft 61 by means of thelink 63 and rod 64,-whichlatteris attached to the head 65 on the said shaft 62. This shaft 62 is givenan intermittent motion in one direction either periodically or semiperiodically at will by some suitable means as the following: Adjacent to the gear 12 on shaft 66 and meshing with the former there is a pinion 66 on the 'main shaft. The pinion 66 operates the reciprocating rack 67 b means of the connectin -rod 68. The rae 67 in turn meshes with t e pinion 69, mounted loosely on the shaft 62,. The pinion 69 has mounted upon its hub 70 the pawl-casing 71, carrying the pawl 72, engagin with the ratchet 73,

- ing the shaft 62.

the head from moving times.

stroke of the rack 67 thepawl will turn the ratchet one-half revolution, thereby operat- On the return stroke of the rack 67 the shaft 62 will remain in a state of rest. By this means the transverse feed .shafts 50 will be operated periodically or once to each complete movement of the machine. When it is desired to operate the said shafts 5O semiperiodioally, a second ratchet 76 is used in addition to the first ratchet, but, unlike the latter, mounted loosely on the shaft 62. This loose ratchet 76 has one tooth 77 of the same depth as the teeth on the fastratchet and another .tooth 78 of a lesser depth. Assuming that the two ratchets are-in the posi= tion shown in Fig. 14, then on the first' forward'stroke the pawl would engage with the tooth 78 and carry the loose ratchet around only, with the result that the shaft 62 would not be moved. In turning the loose ratchet, however, the deep tooth 77 will coincide with one of the teethon the fast ratchet, so that after the return stroke of the pawl and on the next forwardstroke of the same both ratchets will becarried around and the shaft 62 turned. By this means the said shaft 62 is o erated semiperiodically. In connection wit the loose ratchet I employ a brake 79, taking the form of acollar fitting around the hub 89 of the said loose ratchet and pivoted on the pin 81. This is done to prevent the loose ratchet from slipping back on the return stroke of the pawl. As previously indicated, the loose ratchet is removable. When this is done, then the sleeve 82 is reversed, the portion 83 of the same fitting in between the shaft 62 and the brake 79. 'In connection with this transverse-feed mechanism there is employed a stop-dog 84 and a check-dog 85. The stop-dog 84 is pivoted at 86 and is normally held in contact with the notch-87 in the head 65 of the shaft 62 by reason of the spring 88. Mounted on the framework below the shaft 62 is a stud 89, carrying an arm 90, provided with a roll 91,. adapted to engage with the cam 92 on the pawl-easing. In-

terpos'ed between the said stud 91 and the stop-dog 84 are toggle links 93. As the shaft 62, and consequently the head 65, comes to the end of its motion after being moved forward the stop-dog will drop into the notch 87, thereby fixing the limit of the movement positively. The check-dog will now drop into the notch 94 and prevent back on the return stroke of the pawl. As the said pawl returns, however, the cam 92 will act on the roll 91 as it comes to the end of its return stroke, thereby releasing the stop-dog from the head, while the check-(log still remains in engagementwith the head until the next forward stroke. By this means the-movement of the shaft 62, and consequently of-the transverse-feed shaft, is controlled positively at all The motion is imparted to the main shaft 3 from the power-shaft 95 b means of the pinion 96 and gear 97, the atter mounted loosely on the said main shaft. A suitable clutch mechanism '97 is provided on the main shaft to connect it with the gear 97. Owing to the lar e size of the machine, this clutch is operated by a fluid-actuated piston in the cylinder 98 and connected to the said clutch by the levers 99 ina well-known manner. This piston is operated to throw the clutch in by opening a suitable valve in the cylinder 98 by means ofthe pivoted rod 100' and connection 101. Any other means found suitable could of course be used. The spring 102 serves to release the clutch mechanism.

When the clutch is thrown in, the machine commences to operate, moving both the forward and transverse feeds, as well as the punch. It is desirable, however, to be able to operate the advance-feed mechanism independently of the transvcrse-feed mechanism and punch, especially when introducing the stock or sheet of material or for the purpose of adjusting the said sheet. This is accom plislied by the following means: Below the power-shaft an auxiliary shaft 103, carrying the lack-pulley. 104-, having the belt 105 passing over the pulley 106 on the said powershaft. A clutch 107, controlled by either of the levers 108, serves to throw the pulley 104 into operative connection with the :mxiliary shaft, thereby rotating the latter. ()n this shaft is a bevel-gear 100, engaging with the bevel-gear 11.0 on the shaft 111, which carriesthe Worm 112, engaging with the worm wheel 113 on the shaft 6, which in turn. imparts its motion to the shaft 5.

The operation is sufliciently evident from the foregoing description and need not be further enlarged in on. It is desired, however, to draw attemion again to the manner in which thc dill'erent perforations shown in Figs. 15, 16, 17, and 18 are punched out. In Fig. 15 both the forward and transverse feeds act periodically that is to say, in adjusting the machine the latch 15 is moved out of engagement with the pin 13, so that the crank 8 will be constantly connected to the pinion 11, thereby operating the z'ulvamze-l'eed mechanism on every stroke of the machine. l urthermore, the loose ratchet 76 is removed, causing the transverse-feed mechanism to act periodically. In Fig. 16 both the advance and transverse feeds act semiperiodically and alternately. In this instance the latch 15 is moved into engagement with the pin 13,

whereby the cam 20 will operate the advancefeed mechanism scmiperiodically. Also the loose ratchet 76 is introduced on the shaft 62, whereby the traiisvcrsc-l'ecd mechanism acts scmiperiodically. In addition to this, how= ever, and owing to the fact that the'opcration of theadvancc and transverse feed mechanisms alternate, the said loose ratchet 76 is ad justed or turned around a half-revolution on the shaft 62. In Fig. 17 the transverse-feed mechanism acts periodically, and the loose ratchet 76 is therefore left off, while the advance-feed mechanism acts semiperiodically, and the latch 15 is therefore moved into engagement with the pin 13. In Fig. 18 the transverse feed acts semi eriodically, and the loose ratchet? 6 is there ore introduced, but is not adjusted to the position mentioned in connection with Fig. 16, as the action of the forward and advance feed is simultaneous. As the advance feed acts periodically the latch 15 is moved out of engagement with the pin 13. Should it be desired to operate only the advance feed and punch, I simply disconnect the rod 68 from pinion 66 on the main shaft 3, thereby rendering the transverse feed inoperative.
